8 Learning about: Manual Programming ROBOTICS The Engino Robotics Platform (ERP) is a robotic system consisting of a main controller with different buttons, able to connect with various peripherals: motors, lights and sensors. Learn how to program the ERP device manually and create a sequence of commands for traffic lights control. What inputs and outputs are. What a command sequence is. How to program a robot manually. Learning about: ROBOTICS Flow diagram and ERP Simulator A robotic system could not be complete without a programming software. The ERP software is capable of receiving a recorded program from the device or send a program to it. Wake up the dinobot first manually and then through the software by using the ERP simulator, the digital version of the actual ERP controller. How to reverse-engineer a program. How to use the ERP simulator. What a flow diagram is. - Engino Robotics PRO (STEM 70). 1. Find the instructions in pages and build the experimental robot model. Make sure you connect each cable with the correct port. You can also twist the cables around other parts so they do not get in the way. Install 3 or 6 AA batteries on the back of the ERP and power up the device by pressing the On-Off button. 2. Press the buttons (input) on the ERP in exercise 1 and write the results you observe (output). On the motors, place the switch in position II and try both buttons on the ERP. Note that in position O the motor does not work and in position I direction is reversed. 3. A useful function of the ERP is the ability to record the buttons sequence. To test this, press the Program button to record the sequence in exercise 2. To save recording press the Program button again and then Play to test it. You can make many trials until you find the corresponding buttons. 4. Did you notice that there is no delay time between the button pushes during the playback? Read exercise 3 to add this. 5. Use what you have learnt so far in order to create a program concerning traffic lights control. If you are unsure about the correct order you can review it in exercise 4. Engino experimental robot Exercise 1. Push the buttons on the ERP device (input) and write briefly the outcome you observe on the model (output). Input Motor 1 Motor 2 Motor 3 LED 1 LED 2 Buzzer Exercise 2. Press Program (the red flashing light indicates that the program is being recorded) and then the necessary buttons in order to create the following sequence: Ÿ left fan rotates clockwise; Ÿ both fans rotate at the same time in any direction; Ÿ red LED on; Ÿ orange and green LEDs on at the same time. Once you finish, press the Program button again to save the program and then press the Play button to check if the command sequence is correct. If you press and hold the play button for longer time the program will go into loop (endless repeat). Exercise 3. Note that the ERP does not record the elapsed time between the button pushes and it just plays all the recordings without delay. Record again, but this time add delay between each command of exercise 2 by pushing the Idle Time button. Check the results on your model. Exercise 4. Record the following sequence in order to simulate traffic lights control. Don t forget to use appropriate times: Ÿ red light on (cars stop); Ÿ red and amber light on simultaneously (cars ready to go); Ÿ green light on (cars go); Ÿ amber light on (cars ready to stop); Ÿ red light on (cars stop). 31 motor switch in position II motor switch in position II Output - Computer with ERP software downloaded ( and installed. 1.

Upload your program on the computer (see steps 2 and 3). Exercise 2. Drag and drop the peripherals (motors, LEDs and sensors) into the ports of the ERP simulator, according to the dinobot model. Make sure that you set them up correctly as this affects the program and the way your robot will behave. Design them here as well. Exercise 3. In the flow diagram, delete the first motor icon (drag and drop in the bin) and add an Idle icon (from the left). Tick the boxes below to indicate which variables can be changed for each action block. Can you modify...? port time state direction delay Motor LED Buzzer Idle after/ with prev. speed Exercise 4. On the flow diagram make the following changes: Ÿ the eyes light up at the same time and blink 2 times; Ÿ the mouth opens and closes (use only one block); Ÿ there is sound at the same time that the mouth moves; Ÿ there is delay for 2 seconds and then the small legs move; Ÿ the program should repeat for 2 times, not forever. Tip: for this, right-click on the start block to choose the number of repeats, also called loops. 32

9 Learning about: ROBOTICS EnginoRobot app and GamePad There are many ways to control your Engino robots. One of them is through the EnginoRobot application for smart devices with a wireless Bluetooth connection. Try also the Engino GamePad within the software and notice the difference between manual button control and digital programming. How to control your robot wirelessly. Why controlling your robot using digital programming is usually better than manual programming. Learning about: ROBOTICS Functions, touch sensor, IF and IF/ELSE statements Decision making is what distinguishes a real robot from an automated machine. This task is made possible by sensors which receive feedback from the environment helping the robot to decide what action to follow according to its program. Learn about the touch sensor and the IF conditional statement below. How to use functions. How to use a touch sensor. What an IF conditional statement is.

Find the instructions in pages and build the jeep car robot model. 2. Make sure you connect all cables correctly. The touch sensor must be connected in port 3 of the ERP controller. 3. Open the ERP software and follow the instructions in exercise 1. You can use a function block to save the subprogram of moving forward. Once finished, send the program to the ERP and test it. Save it as jeep forward. 4. Add the necessary blocks on the program you just made in order to create the program of exercise 2. Save it as jeep forward-turn. 5. What happens if the model finds another obstacle in its path? Follow the instructions of exercises 3 and 4 to learn about the touch sensor and the IF statement. Use this to program your model, so that it reacts in every obstacle it finds accordingly. Save the program as jeep touch-if 6. Create a more challenging program with the if/else statement in exercise 5. Engino jeep car robot Exercise 1. On the computer, place the correct icons on the ERP simulator according to the jeep car robot model. Drag and drop the necessary blocks inside the flow diagram in order to create the following program: Ÿ the jeep moves forward for 3 seconds and the front LED lights are both on at the same time. Tip: use a function block to save the subprogram move forward. Use the after/with previous command accordingly and set the program to activate only once. Exercise 2. Place an obstacle in front of the jeep car robot. Make the necessary changes on the program of exercise 1 above so that: Ÿ the jeep moves forward for 3 seconds and the front LED lights are both on at the same time until it gets close to the obstacle; Ÿ the jeep moves backwards for 1 second with all lights on; Ÿ the jeep turns 90 degrees to the right with front LED lights on. Tip: in order for the jeep to turn, you can either set the wheels to turn in reverse or stop one wheel from moving altogether. Also, conduct several tests to adjust the appropriate time needed to turn. Exercise 3. Drag and drop the IF statement block in the flow diagram. Right-click on it and write below which variables can be modified (ignore advanced tab) Exercise 4. Use blocks inside the IF statement so that: Ÿ the jeep moves forward continuously and the front LED lights are both on at the same time; Ÿ if the touch sensor is pushed, then the jeep should go backwards for 1 second with all lights on and turn 90 degrees to the right with front LED lights on. Tip: place the blocks that you used in exercise 2 inside the If statement and change the program so that it repeats forever. Exercise 5. Drop the blocks inside the IF/ELSE statement so: Ÿ the jeep moves forward continuously and the front LED lights are both on at the same time; Ÿ if the touch sensor is pushed, then it should go backwards for 1 second with all lights on and turn 90 degrees to the right with front lights on. Else an interrupted beep should sound.

10 Learning about: ROBOTICS IR sensor, WHILE statement and logic gates Infrared sensors are used very frequently in robotics in two very important applications: for distinguishing between black and white colours and for object detection. Try both programming challenges and learn how to configure the IR sensors, how to use the WHILE conditional statement and logic gates. How to use the infrared sensor. What a WHILE conditional statement is. What logic gates are. Learning about: ROBOTICS REPEAT and REPEAT UNTIL statements Doing repetitive tasks with precision is one of the most important features in programming and robotics. We can create a program and make it repeat many times, thus entering into a loop. Find out how to create loops with the ERP and how the robot can get out of it and continue with the rest of the program. What a REPEAT statement is. What a REPEAT UNTIL conditional statement is. - Computer with ERP software installed. - 4 x A3 white carton papers. - Black sticky tape or black marker. - 4 white objects for detection. 1. Find the instructions in pages and build the humanoid robot model. 2. Stick the A3 papers together as to create a big white rectangle. Draw a black ellipse, 5cm thick, using a marker or sticky tape (see picture on the right). You can also download another path at (teaching resources). 3. Open the ERP PRO 1.2 software and follow the instructions in exercise 1, in order to create a black line following program. For this, the two IR sensors should face the ground, so turn them downwards. 4. Read exercise 2 in order to transform your humanoid into an object detecting robot. For this, turn the two IR sensors to face forward. Once you create the program, test it by placing four white objects (as tall as the height of the sensors) as to create an imaginary square for the robot to move along its sides (see picture on the right). Exercise 1. On the computer, place the correct icons on the ERP simulator according to the humanoid robot model. Drag and drop the necessary blocks inside the flow diagram in order to create the following program: Ÿ while the IR sensor in port 2 detects black colour, the motor in port B should move the humanoid forward and both lights should be on; Ÿ while the IR sensor in port 4 detects black colour, the motor in port A should move the humanoid forward and both lights should be on. Once you place the appropriate blocks, you will need to configure the infrared sensors, so that they follow black line. For this, consult the user manual under the section Sensors / Infrared sensor configuration in pages With this program the humanoid will follow a black line. In order to test your program, place your robot on the black ellipse you created and see if it goes around with its lights on. Exercise 2. Drag and drop the necessary blocks inside the flow diagram in order to create the following program: Ÿ humanoid moves forward; Ÿ if it detects a white object with either sensor or both, the robot should stop and warn with beeping sound and lights on; Ÿ after 5 seconds the humanoid should turn 90 degrees to the right in order to detect the next object. Tips: the angle is always the same, so only one program is needed for turning. To set both or either sensor to detect objects you must choose the appropriate logic gate (AND or OR). You should also configure the sensors again so they will activate on object detection this time. - Computer with ERP software installed. - 4 x A3 white carton papers. - Black sticky tape or black marker. - 1 small water bottle (half full with 250 ml). 1. Find the instructions in pages and build the grabber robot model. 2. Follow exercise 1 in order to create a loop program using the repeat block. 3. Sometimes we need a loop to be executed continuously until a sensor s condition is met. Follow exercise 2 to learn how to do this using the repeat until block. 4. Stick the A3 pieces of papers together as to create a big white rectangle. Draw a black half circle ending with two vertical lines and a red circle, as you see in the next picture. Or download this at (teaching resources). The grip should be in the circle when the grabber stops on a line. Place the bottle on the red circle. 5. Read exercise 3 in order to make a robotic carrying device that would pick up the bottle and take it to the other side. Exercise 1. On the computer, place the correct icons on the ERP simulator according to the grabber robot model. Drag and drop the necessary blocks inside the flow diagram in order to create the following program: Ÿ the grabber should move forward for 2 seconds precisely. This should be repeated 5 times. Ÿ when the loop finishes the buzzer should sound for 2 seconds. Tip: change the variable of the start block from forever to 1 and use the repeat block to create the program. Exercise 2. Create the following program (the grip of the grabber should be open at the beginning): Ÿ the grabber should move forward continuously until the touch sensor is pressed. Ÿ when the touch sensor is pressed, the grabber should stop and the grip should close with beeping sound. Tip: change the variable of the start block from forever to 1 and use the repeat until block. Exercise 3. Create the following program (the grip of the grabber should be open at the beginning): Ÿ while the IR sensor in port 2 detects white colour, the motor in port A should move the grabber forward; Ÿ while the IR sensor in port 4 detects white colour, the motor in port C should move the grabber forward; Ÿ if the touch sensor is pressed, the grip should close and grab the bottle. Then the grabber should turn around for a specific amount of time until it finds the black line; Ÿ the program will be considered successful if the model reaches the other black line. With this program the grabber will follow the line by avoiding the black colour, pick up the bottle and go back. Place your model on the paper and see If it works.

11 Learning about: ROBOTICS Real-life example: pedestrian crossing After experimenting thoroughly with all features of the Engino Robotics Platform, you are now ready to put your knowledge into practice! This can be achieved by programming real-life example models, just like the one of pedestrian crossing that follows. Can you make sure that Engino-man crosses the road safely? How to program a real-life example of pedestrian crossing. What safety requirements should be followed. Learning about: ROBOTICS Real-life example: automated house Another real-life example is the automated house. One of the main advantages of using robots is their ability to work only when specific conditions are met. This can come in handy if we want the air-condition of a house to work only when doors are closed, thus saving energy. Can you simulate the same? How to program a real-life example of an automated house. How to make a building more energy efficient using robotics. - Computer with ERP software installed. 1. Find the instructions in pages and build the pedestrian crossing model. You will find the carton paper for the road inside your Robotics package. 2. Follow exercise 1 in order to simulate the main traffic lights control for the cars. 3. Programming real-life traffic lights is a very important task. People entrusted with this, need to make absolutely sure that when one light is green the vertical side light is always red. This way cars or pedestrians will never cross each other s paths. With this in mind, add the pedestrian crossing lights in your existing program by following exercise Here comes Enginoman wishing to cross the road! To do this safely he must use the pedestrian crossing. Follow exercise 3 in order to create a program that meets all the safety requirements. When you finish, tick the boxes below for every point you got right. Exercise 1. On the computer, place the correct icons on the ERP simulator according to the pedestrian crossing model. Drag and drop the necessary blocks inside the flow diagram in order to create the following program that simulates main traffic lights control for the car (don t forget to use appropriate times): Ÿ green light on (cars free to go); Ÿ amber light on (cars ready to stop); Ÿ red light on (cars stop); Ÿ red and amber lights on at the same time (cars ready to go); Tip: if you put the program into loop, there is no need to add green light as a final step, as it already exists in the beginning. Exercise 2. Make the appropriate changes on the program of exercise 1 in order to add the pedestrian crossing lights. These will work in parallel with the main traffic lights so that: Ÿ when is green light for cars, it should be red for pedestrians; Ÿ when it changes to amber light for cars (ready to stop), it should still be red light for pedestrians; Ÿ when it changes to red light for cars (stop), it should be green for pedestrians (go); Ÿ when is red and amber lights for cars simultaneously (ready to go), light should change to red for pedestrians. Exercise 3. Make the appropriate changes on the program of exercise 2 in such a way that: Ÿ the lights interchange between the pedestrian crossing lights and the main traffic lights should occur only if the pedestrian pushes the button. Tips: read the safety requirements below and adjust your program accordingly. Remember that before the interchange, lights should still work! - Computer with ERP software installed. 1. Find the instructions in pages and build the automated house model. With the remaining parts you can create again an Engino-man (page 65, step 6), who will trigger the sensors of the house. 2. When building a house, usually the wires are inserted inside the walls for safety and aesthetic reasons. Twist the wires of your model around the columns of the house to simulate this, but keep the same ports. 3. Besides wiring, another problem is to construct buildings that are as much energy efficient as possible. And by this we mean that the house should use power only when is needed and at the least amount possible. Follow exercises 1 and 2 in order to create an energy efficient robotic house. 4. You can make your Engino model more energy efficient structurally if you close the walls entirely or even place an Engino solar panel on the roof (available in solar set). Answer question 3 about real-life houses efficiency, but from robotics perspective. Exercise 1. It is a hot summer day! Engino-man is returning to his house after a pleasant walk at the park. Tired as he is, he wonders whether is it possible to install an automatic system that would open the front door at the press of a button. Can you help him? On the computer, place the correct icons on the ERP simulator according to the automated house model. Drag and drop the necessary blocks inside the flow diagram in order to create the following program: Ÿ if the touch sensor is pressed, the motor should open the door. Tip: note that the motor should work accurately so that the door will not close back. Exercise 2. Engino-man can now enter his house in automatic way. But why stop there? He thinks that it will be nice if there was a way for the house to sense his presence so that the door would close back and some devices would start working after. These can be the air-condition (simulated by the fan) to cool his house and the LED light to brighten the room. Can you be so kind to help him again? Make the appropriate changes on the program of exercise 1 in such a way that: Ÿ if the IR sensor detects motion inside the house, then the door should close back. After this, the fan should start working and the LED light should be on. With this program you save energy because the air-condition works only if the door is closed, keeping the cool air inside the house. You can make your program more energy efficient if you add minimum time for the fan to work. In real life, airconditions stop when a pre-set temperature is reached. SAFETY REQUIREMENTS: Is the amber light s time adequate enough to warn car drivers to stop? Exercise 3. Can you think of some other ways to make real houses more energy efficient using robotics? Do the lights interchange in the correct order, not conflicting with each other? For example, green light for cars and pedestrians should never occur simultaneously. Is the green light s time adequate enough for pedestrians to cross the road? Engino pedestrian crossing Did you add buzzer sound to warn pedestrians when to go? Engino automated house 37 38

12 ERP Manual Engino Robotics philosophy The Engino Robotics Platform (ERP) is specially designed for Primary and Secondary school children, taking into account the latest technological trends and the most modern pedagogical principles of learning. Intellectual development is approached in a spiral way, helping students to reconstruct their ideas formed based on their existing knowledge merged with new information, acquiring higher order concepts and taking it to the next level. The innovative ERP controller in conjunction with the patent pending ERP software are ideal for ICT teaching, allowing various levels of robotic programming to be implemented in a fun and challenging way. Two innovative ideas make the patent pending Engino Robotics Platform a unique teaching tool! Firstly, the ERP allows five interconnected ways of programming, so the users can choose the method that suits them best according to their age and experience. Each method is described briefly below and in more details with programming examples in the following pages. Secondly, parallel programming (doing tasks simultaneously) has never been easier with the introduction of the After/With Previous variable in every block of the ERP software. Five programming methods Manual ERP programming The ERP device is designed in such a way that it allows manual program recording through simple button press. The user can easily push the Program button in order to record any desired sequence of commands, one by one or simultaneously, which is then saved on the device and can be reviewed after by pushing the Play button. This first level of programming is about interacting physically with the learning material, using a method (pushing buttons) that all children are familiar with. The programming procedure provides immediate visible feedback, enabling the user to adjust the time and order of the commands through unlimited number of attempts. Text Editor Most advanced programming languages based on text and visual representation of commands may become difficult as the program becomes bigger and more complex. The Text Editor is using a pseudolanguage created specifically for the ERP. It has many familiar terms of programming languages (such as START, END, IF etc). It is the ideal tool for introducing advanced programming, as it allows the user to have a quick review of the program and edit the variables easily. Smart device application Complying with modern technological advancements, the ERP can also be controlled with a smart device (mobile or tablet) that runs on either Android or ios operating system. The user may download the EnginoRobot BT app, free of charge, available on Google Play or Apple Store. The app simulates the actual controller and can be used wirelessly, once the ERP is connected with the smart device over Bluetooth. Flow diagram Once a program is created manually on the controller, it is impossible to edit through the controller. The user must record it again in order to adjust the commands. Also, there is no way to add advanced programming features like If statements and While loops. This can only be done through the Flow Diagram, the main programming feature of the ERP software. In this window, the user can program complex commands and take full advantage of the robot s capabilities and sensors. The Engino robotics is designed for the gradual transition from physical manual programming to abstract software control, by applying an innovative reverse engineering method! The receive button uploads the manual program from the device into the PC in the form of pictorial flow diagram and text! This can be edited and fine tuned as needed. Then, the user can click the send button in order to import the program back to the device for testing. ERP Simulator The ERP Simulator is a special window within the ERP software that simulates the functions of the actual controller, though the buttons in this case are digital instead of physical. Once the computer is connected with the ERP (through USB), the user may record a program using the Program button and get a visible feedback from the robot as before. The great advantage of this method is that while the program is being recorded, the commands are transferred into the other two windows of the software: in the Flow Diagram, as visual blocks and in the TextEditor, as lines of text of a special pseudolanguage (not actual programming language). Parallel programming The second main innovation of Engino in educational robotics is the function of parallel programming. The Engino Robotics Platform software uses visual programming (blocks with symbols instead of text), which contain an innovative After/With Previous variable that provides the parallel feature. The user can choose between after previous if he/she wants the command to be executed when the previous command is finished or with previous if he/she wants the command to be executed at the same time. The blocks that work in parallel are joined together with a coloured line. This reduces the complexity of programming in a great extend, as the order of commands become more clear and easy to formulate

13 ERP controller The Engino Robotics Platform (ERP) is a robotic system consisting of a main controller with different buttons and indicators, able to connect with various peripherals: motors, lights and sensors. The ERP is a powerful and flexible tool that is easy to use and can connect with the rest of the Engino parts! In this manual you can find all the necessary information about: how to program your robots with illustrated examples, the main features of the ERP controller, how to install the ERP software, how to update the firmware, safety guidelines, tips and much more. But first, see below the various buttons, ports and peripherals of the ERP. Peripherals and ports: different types of peripherals work only in specific ports of the ERP controller, as indicated below: Peripherals Motors Ports to connect A, B, C The motor does not work if the switch is on position O. In position II the motor works in the direction of the ERP controller. In position I the direction is reversed. Motors do not need extra batteries to work. LED lights 1, 2, 3, 4, A,B, C MOTOR BUTTONS Press these buttons to turn the motors clockwise. SENSOR OR LED PORTS MOTOR OR LED PORTS LED BUTTON LED BUTTON Press this button to light up the connected LED. MOTOR BUTTONS Press these buttons to turn the motors anti-clockwise. Press this button to light up the connected LED. SENSOR OR LED PORTS Touch sensors 1, 2, 3, 4 InfraRed sensors 2, 4 Manual ERP programming Connect RJ cable here Connect RJ cable here Connect RJ cable here The ERP, once switched ON, can be operated manually by pressing the various buttons in real time. To begin manual recording press the Program button once. The red flashing light indicates that the ERP is in record mode. In order to create a programming sequence, press the buttons of the LEDs, Motors, Buzzer or Idle Time at any desired order, either separately or simultaneously. Each step is recorded for a period of time that the button is being pressed. When the programming procedure is finished, press again the Program button to save the program in the controller s memory. Press play to start the program; if you hold it for 3 seconds the program will repeat in a loop. Note that the device can save only one program in its memory. You can also operate the ERP without setting it in record mode; just press the buttons and it will work as a controller in order to see how the various outputs work. PROGRAM BUTTON Only for manual programming. Press this button to start recording. Once the red light starts blinking the controller goes in record mode. When you finish, press the same button again to store in memory. IDLE TIME BUTTON This button has two functions: - it adds idle time during manual programming; - press once to activate the Bluetooth when the controller is switched on (but not in recording or play mode). Open the EnginoRobot BT app, find the ERP Bluetooth network and connect. Note that if the ERP is not connected with any Bluetooth device within 1 minute, it will turn off to save energy. Batteries: To turn on the controller you need to install 6 new AA batteries (it works also with 3 batteries placed continuously up or down). You will need a cross-head screw driver. Unscrew the battery cap at the back of the controller. Place the batteries carefully making sure that the + and - signs match those indicated in each battery position. After you place the batteries, screw the cap back in position if you want. USB PORT for computer connection ON/OFF BUTTON ATTENTION: PLAY BUTTON Press the button once to start the program. Press and hold the button for 3 seconds to repeat the program in a loop. BUZZER BUTTON Press this button to play a buzzer sound. Bluetooth must be turned off in order to turn off the device smoothly. Also, make sure that the USB cable is not connected. Safety guidelines: Do not mix alkaline, standard or rechargeable batteries. Non-rechargeable batteries are not to be re-charged. Do not mix old with new batteries. Remove dead or old batteries from the ERP if they will not be used for a long time. Never dispose off batteries in fire. Supply terminals are not to be short circuited. Recording example 1: Connect 2 motors in each of the ports A and B and 2 LED lights on ports 1 and 3. The peripherals will run for as long as their buttons are pressed. You can try to press the Buzzer as well. For the program, the motor in port A should move clockwise for 3 seconds, the LED in port 1 to light up for 5 seconds, the motor in port B to turn anti-clockwise for 3 seconds and the LED in port 3 to light up for 5 seconds. Instructions: 1. Press the Program button to begin recording (a flashing red light should be on). 2. Hold pressed the clockwise button of the motor 1 in port A for 3 seconds. 3. Hold pressed the button of the LED 1 in port 1 for 5 seconds. 4. Hold pressed the anti-clockwise button of the motor 2 in port B for 3 seconds. 5. Hold pressed button of the LED 2 in port 3 for 5 sec. 6. Press the Program button once to save the program in memory. 7. Press the Play button to run the program. 8. After the program finishes you can repeat it continuously in a loop if you hold pressed the Play button for 3 seconds. Note that the delay time between button pressing is not recorded. While the program is in play mode each command follows the other without any time delay. If we want to have a time delay between steps then we can use the Idle Time button. For as long as the Idle Time button is pressed, interval time is recorded between steps Recording example 2: The ERP also allows many commands to play simultaneously. For example you can press two or more buttons at the same time and they will play together. Repeat the same sequence as in example 1, but this time follow commands 2 and 3 simultaneously. Then press and hold the Buzzer for 2 seconds; then press the Idle Time for 5 seconds and carry out commands 4 and 5 simultaneously. Finally, save and play (commands 6, 7 and 8).
